Includes RTH-750 Rotor with extra buckets and carriers Fully tested to -15C The Sorvall RT7 Refrigerated Centrifuge combines the features of the tabletop centrifuge and those of the larger refrigerated centrifuge in a compact tabletop instrument. It is similar to other Sorvall tabletop centrifuges, with an added refrigeration system that consists of an evaporator/rotor chamber and a low-temperature condensing unit. The RT7 features digital readout displays, a closed-loop speed control, and has a tachometer port that allows rotor calibration. The chamber door is counterbalanced for easy opening and safe closing. The gyro-action, self-centering drive has a hex drive spindle which assures proper seating of rotors. This centrifuge also has a slow-start feature that slowly accelerates the rotor from 0 to 500 rpm. This rotor has a maximum capacity of 4 x 750ml and can reach speeds up to 4,000 rpm and 3,313 x g.
